Arrandale 32+45nm to have a 35W TDP

We finally managed to get some details about Arrandale, dual-core Nehalem based 32nm CPU with 45nm integrated GPU packed in multi chip packaging.

The official number is 35W for the dual core 32nm CPU and
its 45nm IGP graphics. This is far from being cool but its not that bad either. At the same time, the Calpella two chip platform will offer a 38
percent area saving over the Montevina platform, which probably means that
notebooks could become smaller and thinner.

To paint a better picture, a T9400 Core 2 Duo at 2.54GHz has
the same 35W TDP, while T9600 at 2.66GHz can maintain 25W TDP.

The GM45 consumes 12W which gets the whole notebook platform
to 47W before we add the TDP values of the Southbridge that is at least
additional 5W. Arrandale will get things better as the whole CPU and graphics will
get you to 35W TDP, but Intel’s ultra low voltage CPUs can have a TDP of 10W
and Arrandale cannot really compete with that.

There might be slower clocked Arrandale that will get its
TDP to twenty something values that might find its place to Ultra low voltage
market.
